It would be even better if it could change between a few different "themes". Different tracks from Manhunt would be great, just to keep things fresh. Possible randomly select the theme, which would be separated by directory I guess. You could probably detect how many times the track has looped, give it a very generous amount of times to loop, and then detect when the music is only playing the bottom layer of the track (0 - Always On) for about 8 seconds, and the player isn't wanted (to double check) and perhaps to make sure there aren't cops in the area if it's worth it to make the transitions more seamless, then you fade out, and then fade in the next track in another directory, same file setup.
